Are considered synonyms (as Hygrocybe)on page 55 of Waxcaps of Eastern North America.

I should point out that Hygrophorus pratensis is the type species for the genus Camarophyllus. DNA testing seems to show that it belongs to its own section near the “Omphalina group”, Pseudoclitocybe cyathiformis and Cantharocybe gruberi are part of this group.
Thanks Irene, its been a pleasure.

I appreciate

that you want to set things straight, Herbert! I have seen this placement of Ampulloclitocybe before, splitting the Hygrocybe species – but maybe it was a premature decision to give it a new genus name then? Maybe it just should have been moved to Hygrocybe instead?

For some reason, neither IndexFungorum nor MycoBank use Camarophyllus as a current genus name. It could be nomenclatoric issues, or just that more work needs to be done to set the limits to that genus and sort out which species that actually belong there.
But I also beleive that it will be a name change in the future, and it doesn’t really matter what we call them right now.

And yes, Camarophyllus borealis is described from America. Perhaps that’s why there are american authors that consider nivalis and virginea to be synonyms of borealis :-)

If you click on Camarophyllus it goes into some detail about the name.

I have read the original, and as you can see “pileus not viscid”.

Regarding H. virgineus, is it the same species we have in North America?
“In the European plant the surface of the pileus is said to become floccose when dry and sometimes to crack into small areas, but these characters have not been observed by us in the American plant.” http://books.google.com/...

Camarophyllus borealis is an American species, it was first discovered here.

I don’t know where you got the description of Peck’s borealis from, but here’s his original description (from the “Twenty-sixth Report on the State Museum”):

“Pileus thin, convex or expanded, smooth, moist, white, sometimes striatulate;
lamellae arcuate-decurrent, distant, white;
stem smooth, equal or tapering downwards, stuffed, white.
Plant 2’ (5 cm) high, pileus 8”-12" (2-3 cm) broad, stem 1" (2,5 mm) thick.
Ground in woods. Croghan and Copake. September and October.
The species is related to H. niveus but the pileus is not viscid."

Have you got any links to recent DNA works that can tell us why Camarophyllus should have genus status – and which species it includes?

Recent DNA

has shown Camarophyllus to be worthy of genus status.

True, I can’t see any evidence of DNA tests on a type collection of borealis. If there is one, it’s probably too old to retreive any sequence from it anyway. There’s a wide consensus about both niveus and borealis being synonyms to virgineus. But you are right Herbert, this/these white species (cap viscid, moist or dry..?) in the section Camarophyllus are in need of investigation, including the many colour variations of it/them.

And yes, Camarophyllus has been published, but many authors prefer to let it stay as a subgenus as it was from the beginning.

By: Erlon (Herbert Baker)

But Camarophyllus is valid genus and as far as I know there is no DNA work that backs synonymy between the two species mentioned.

H. virgineus is slightly viscid and is not as stocky in proportion.

Camarophyllus borealis on the other hand may trick you into thinking you have a white chanterelle.

I believe Camarophyllus borealis is synonymous with C. virgineus and as we have discussed before it it still Hygrocybe at Index Fungorum.

By: Erlon (Herbert Baker)
2011-03-07 08:06:25 PST (-0800)

has been published, why would it need to be republished? Is there DNA work that shows the synonymy your suggesting? thanks!

The current name
By: Irene Andersson (irenea)

is Hygrocybe virginea. Camarophyllus borealis is a synonym (I think the name of the genus is still pending).

I suspected these were not white chanterelles

They did not smell like choice edibles. Hygrophorus seems promising, but the flesh is not at all waxy or slimy; it is dry and feels like a chanterelle. This is the only population of these I have ever run across. They came up in the same spot last year, but a little later in the season.
